A systemic herbicide, fluridone, has been developed which can provide effective control of hydrilla; this control usually lasts for about one year. Hydrilla control using fluridone in lakes of central Florida. Most introductions are likely to derive from the aquarium trade (Madeira et al., 2000). World Checklist of Hydricharitaceae., Richmond, UK: Royal Botanic Gardens, Kew. Due to its tolerance of low light conditions (White et al., 1996), it is capable of growing in water up to 7 m deep (Yeo et al., 1984).
